Here’s a scenario to warm the cockles of an opposition leader’s heart: Prime Minister Stephen Harper, his back to the wall after months of scandal, shorn of allies because of his harsh treatment of former chief of staff Nigel Wright, isolated within his own party, finally realizes victory in 2015 is beyond his grasp. Perhaps with a not-so subtle push from senior figures within the Conservative hierarchy, he takes a walk in the snow.

Details of how Prime Minister Stephen Harper’s staff allegedly tried to manipulate a Senate committee report and an independent audit were laid out in an RCMP affidavit filed last week in court.

Conservative sources familiar with Chong’s bill say it’s not a direct reaction to what’s currently in the news, and wouldn’t even come into effect until after the next election. Chong had been forced to introduce the bill or risk losing his place in the order of Commons consideration.

When asked about the bill Friday, Chong said, “I’m going to wait until the bill is introduced in the House before providing public comment.”

One measure would entrench in the Parliament of Canada Act that the different Commons caucuses — also referred to as parliamentary parties — have the power to trigger a leadership review vote, as long as 15% of the caucus applies in writing for one.

After that, a simple majority of MPs, 50% plus one, could vote to turf the leader and have a leadership race.

Members of Australian’s Labour party caucus recently used that power to eject leader Julia Gillard, and Conservative MPs in Britain have the same power.

In the case of Chong’s bill, the power would be restricted to the House of Commons caucus, and not the larger national caucus that includes senators.

Theoretically, the MPs would be cautious about how they vote because of their new, closer relationship to the riding associations that helped send them to Ottawa. The idea would also be to make political engagement more attractive to Canadians, with the knowledge they have more power at the grassroots level.

Commons caucuses would also have the right to elect their own chairs and to call for a review of an MP, as well as to eject or readmit them.

Right now, it is the prerogative of the leader alone _ as Harper showed this year when MP Dean Del Mastro was shown the door after being charged under the Canada Elections Act.

Chong’s bill is expected to be introduced next Thursday, and would potentially see second reading debate in February or March.

There is a quiet but substantial section of the Conservative caucus that has bridled against Harper’s control, which has extended to their questions and votes in committees, and what they say on the floor of the Commons.

This spring, they rallied behind MP Mark Warawa’s bid to give MPs the right to make statements of their own choosing in the Commons.

MP Brent Rathgeber left the Conservative caucus in June, complaining about the gradual transfer of power from members of Parliament to the Prime Minister’s Office and cabinet.

Chong is a popular figure in the Conservative caucus, regarded as a moderate and measured straight-shooter with a lot of integrity.

He himself resigned from a cabinet post in 2006, saying he did not agree with a government motion recognizing Quebec as a nation.

In order for Chong’s private member’s bill to fly, he will need more than just the support of his own colleagues — MPs from other parties will also need to come on board.
